NFS File System, properties

• A NFS can be mounted only if the server recognises the client by its primary name (according to the server hostfile matching the primary IP address).

• An NFS demon (nfsd) acts on the server on behalf of the NFS client regarding FS operations and acquires necessary locks on the server.

• Shutting down the server without unmounting clients can turn client processes into zombies entering a kernel mode (kill -9 is ineffective). The only way to kill those zombies is to shutdown the client.
